Over time most PCB designs need to change – a mistake is found, or a part becomes obsolete, etc. Typically once the changes are complete, a new set of manufacturing files (Gerbers, NC Drill files, BOM, Pick and Place, etc) are generated, and the updated design is stored as separate version within a version control system. Using a version control system makes it possible for design teams to go back later and compare differences between design versions.
What if there is no access to the version control system, and you only have the manufacturing files? How can you tell the differences between revisions of the same board?
This article will demonstrate how to quickly identify differences between two similar revisions of the same design, using only the manufacturing files.
Import Manufacturing files, and Create a New Job.
Typically if you're starting FAB 3000 you'll have a blank screen with an empty job already created, so lets use that default job to import our first set of manufacturing files.
Perform Job Comparison
That's it, you now have the ability to tell the differences between revisions of the same board.
